gineer, a subject of the King of Great Britain:

and Ireland, residing ,at No. 116 Canning street, Carlton,.in the British State of Victoria, Commonwealth of Australia, have invented a new and useful Improved Machine. for Use in the Manufacture of Horseshoes and the Like, of which the following is a specifiand the latter from the nose or front end 0, Fig. 7, both views showing the former-die cation. V

This invention consists of an improved machine which has been designed mainly for use in the manufacture of horseshoes. In it a heated 'bar or rod of iron, steel, or other metal of the proper length and se'ctional area is bent to the requisite'shape and section about a sliding die or former byflanged compression-rolls; also, the curved? creases and nail-head countersinks may'be formed in the under face of horseshoes. Said sliding die works in a suitable guide in a bed-plate and has a reciprocating motion imparted to it by an eccentric, while theflanged compression-rolls are acted on by spring and cam operated levers, the'cams being on the eccentric and the horseshoe when finished being delivered over the end of bed-plate by reason of the peculiar hinged formation of the die upon its reaching the end of its stroke. The machine can be also fitted, if desired, with a pair of rotary dies, which may either be used to prepare blanks for the abovementioned sliding die and compression-rolls when they are to be used only forforming the creases in the under face of horseshoe or the rotary dies may be used for making horseshoes of a smaller size, a similar flange compression -roll being employed in both instances. In this machine both sets of dies are worked simultaneously.

The invention will now be described, aided by a reference to the accompanying sheets of in g the cam contactwith'theside-lever friction-roller; Fig. 6 is a detail sectional view showing the sliding former-die at end of its the sliding former-die'and flange-rolls by themselves and Fig.7" a side view of the sliding former-die by itself-with itsv hinged front piece down. Figs. 8 and 9 are sectional views, the former taken on line b b, Fig. 7,

block as fitted in guides in the bed-plate. It will be noticed that Figs. 7 to 9 are drawn to a larger scale than the other figures for the sake of clearness.

A is a bed-plate providedwith a central longitudinal gap or slot A, the left-hand end of which has projecting guidesAHo fit recesses b formedin the sidesof the sliding former or die block B B, which is connected at c byrod O with the eccentric-strap O of theeccentric C securedon shaft D, carried in bearings A on said bed-plate. Shaft D has a spur-wheel Dlkeyed on it which gears with a pinion D on another shaft D also carried in bearings A on bed-plate A, while at other end of shaft D are the driving-pub. leys D If so preferred, acrank may be employed in place of the eccentric O 0 above described.

The sliding former or. die block B has an upper central piece-b secured to it, the shape and size of which are similar to that which the internal edge of the horseshoe is to take, while the block has around the piece I) a similarly-shaped marginal flange 12 which forms a bed for the metal bar to rest upon while being workedto the requisite size and shape, also-to form the creases or curved re,- cesses in under surface of the horseshoe. Projections or ribs b? are formed on the surface I) of the former-die B, and further shallow studs 12 are provided to form thecountersinks for the nail-holes. The outer edge and top surface of the horseshoe are formed by the flange compression-rolls E, the smaller diameter e of each of which bends thebar upon the die-piece 17', while the fiangeclof said rolls E rolls the metal tothe properthicka ness and for which purpose the outer edge of I00 the flange of each roll is chamfered or beveled off at 6 as shown in Figs. 8 and 9. The flanged compression-rolls E are centered on studs E, carried by upper levers F and lower levers F. Die-block B has its front part B hinged to the back part at B in order that when the end of the outstroke is reached it will fall over end of bed-plate, as shown in Fig. 6, and so automatically deliver the finished horseshoe.

The upper part Z) of the former-die may either be made solid with the slide-block or be fixed upon it, and at its fore end it has a projecting finger 79 which holds the bar to be shaped in position. The dotted lines (marked G) indicate the position that the straight bar to be operated on is placed, it being set in proper transverse position by aid of the adjustable fence G. (Shown in Fig. 2.) The levers F are centered at F on studs carried by the bed-plate and by upper brackets F while at other ends of the levers are friction-rollers F which travel on upper surface of bed-plate, the said friction-rollers being acted on during a portion of each rev0- lution of the eccentric by cams C one on each side of the eccentric, and it is by said cams acting on the levers that the flanged compression-rolls E are pressed hard upon the heel portions of the horseshoe and die.

In this machine by varying the height from the flange 19 to top of die B B horseshoes of a tapering thickness may be produced.

The lower levers F are centered on studs 5 f, projecting from under surface of bed-plate,

/ and the back ends of said levers are acted on by springs F which are also secured to the bed-plate and are designed to press the compression-rolls E, through the medium of the levers and the pins E, against the former or die block B B. Under the levers F at f ball or antifriction-roller races may be arranged to lessen the friction while the levers are in operation.

The rotary former-die H, hereinbefore referred to, is affixed on end of shaft D, while the flanged compression-roll E is carried by a stud on a lever J, centered at J on a bracket J secured to bed-plate A and working in a vertical guide J also secured to bed-plate, said lever being acted on by a weight J The flanged compression-roll E used with rotary die H is identical with those marked E, already described, and hence needs no further description, while the said rotary die H has also a part 7% on it to form the internal shape of horseshoe; but in this case a pin H is pro vided to hold the starting end of the bar G, whichiis to be formed into a horseshoe by the rotation under pressure of roll E upon the rotary die H. To eject the finished horseshoe, sliding pins h are provided, which pass through holes in flange of die H, the outer ends of said pins being secured to a carrier 72 which is acted on by a spring h and said carrier just prior to the die completing its revolution contacts with the fixed projection 7r, borne by the bed-plate, and so projects the pins from their holes, and thus forcing the horseshoe from the die.

From the foregoing description it will be readily understood that the bar G to be operated on by the sliding block B B is pressed forward against the flanged compression-rolls E, which are forced toward one another by pressure derived from the springs F until such time as the cams C contact with friction-rollers F and such increased pressure upon the rolls E completing the back or heel part of the horseshoe the die B then continues its travel forward to the end of its stroke and allows the hinged fore part B to pass beyond the end of its guide on bed-plate, when it falls, as shown in Fig. 6, and so delivers the horseshoe.

The blank-bar G (shown in dotted lines in Fig. 2) is placed while in an intensely-heated condition on the nose of the former-die B, and as the die moves forward said blank is acted upon simultaneously by the swagingrollers E, the portions 6 thereof bending the blankhorizontally to the shape of the vertical edges of the die B, while the beveled flanged portions of said rollers swage or crush the intensely-heated blank down on the ledge or bed 19 of the die B and onto the ribs and projections b and b.

It will also be obvious that articles of other or somewhat similar shape to horseshoes may be formed in this machine by furnishing it with dies and rolls of the requisite shape and sectional form. v

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
